Removal of dashboard components may be required, and if you don’t know how to remove the parts properly, permanent damage may occur. In some cases, you may find two pairs of holes or slots on the left and right of the face of the radio. These are called “key holes” and will require a special tool that can be purchased at most car audio stores or online to release the head unit.

Do not cut an ISO Mount kit and install the metal radio sleeve! If you cannot find the screws you can usually purchase them at your local car audio shop. Make sure they do not exceed the maximum limits the manufacturer specifies or you will damage the radio.

Strip approximately two inches insulation off of all of the wires and twist matching wires together. This provides superior surface area connection to crimping and more flexibility than soldering. Cover the splice with electrical tape or a twist on wire nut If you have any trouble matching the wires, follow the steps provided with the wiring harness adapter. The wires on the harness adapter and plug are usually color coded or tagged for easy identification and matching. Some solder has lead in it, so avoid breathing in the fumes when you solder.

Connect to the radio’s wiring harness or harness adapter directly to the vehicle’s wiring harness. It is designed to simply plug in. Connect the antenna wire to the back of the radio. This rarely, but occasionally, requires an adapter. If you don’t have an adaptor. You will need to connect and [identify the wires][1] from the car’s harness clip and stereo one at a time. To do so, use the repair manual for your car or find a wiring diagram online. The power wire from the stereo is typically red, whereas its corresponding wire from the car is usually black. The constant power wire for the stereo is usually yellow or blue, and the remaining wires will connect to the speakers. To secure all connected wires, you can solder them together, twist them and cover with heat-shrink wrap or electric tape, or get connectors that slide both wires in and crimp or twist them together.
